Were you awake very much last night? I see at least one break in therapy so I know of at least one.

The 00:45 cluster....do you think you might have been awake then?

Try 11.5 cm pressure tonight.

I often flop back and forth side-to-side during the night, and I remember doing so but not when. If I awake enough (like for the bathroom), I'll turn the machine off for a little while. The Pillow sleep app suggests I was awake a before 1 am (a terrible graph scale) and for a bit before 2 am, when I turned off the machine. (I can't seem to get the audio recording to work.)

11.5 for tonight it is!

Hi,

I'm back with some more data (two nights) at the new pressure setting of 11.5 (up from 10.5). I'm thinking of going to 12.5 as the clusters of events seem to occur when I am awake or in REM. For example, using the Pillow and SnoreLab apps, on Feb 26 I rolled over at 2:34:23 am and coughed at 2:34:36 am (which I remember doing). I awoke at 4:15 am and don't think I fell back asleep (smart watch app says I was awake). On Feb 27, I rolled over at 12:22 and coughed 30 seconds later. The Pillow app indicates that I was in rem sleep from 2-2:30 am and from ~3:30 am to ~4:30 am during those clusters of events.

Seems like a lot of false positives, but maybe go to 12.5 to clear of the ones which occur when I am "sleeping." Does sound reasonable? I am having my first visit since starting on the CPAP with my sleep doctor in a week and a half, and want to have a robust discussion.

Thank you!

Be aware that no amount of increasing the pressure is going to reduce any awake flagged events...those aren't real...the airway isn't really closed off despite the machine telling you it is. If you know you were awake you have to mentally remove those events from your evaluation of pressure needs.

Now if you are for sure you were asleep...and maybe in REM or on your back...more pressure is the fix but don't go increasing the pressure and expecting the awake flagging to stop...it won't.

Well, the airway might be closed, it's normal to close off the airway sometimes when holding breath... But as you say, those don't count, because you're not asleep, no matter what the event is flagged as.

What does cause the awake flagging? I don't seem to get any anymore. I used to when I first started. I've never understood why so many people get awake apneas. I sometimes have the mask on an hour before I actually go to sleep, but nary an apnea happens during that time.

Thank you! I'll try and be careful to not count awake events. In my case, I normally pause after breathing out and that is what I think the machine is counting.

I am hoping that between the two sleep apps (SnoreLab and Pillow) help identify when I might be awakre. I just wish they had better export functions so i could overlay their data onto the SleepyHead charts.

Cheers
